[求助]求救：请各位jsp高手帮忙
写了一个连接到数据库读取数据的jsp文件，但是在tomcat下运行的时候，出现了下面的错误：
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:845) org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:778) org.apache.jsp.connect_jsp._jspService(connect_jsp.java:77) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
root cause
java.lang.OutOfMemoryError
note The full stack trace of the root cause is available in the Apache Tomcat/5.0.29 logs. 部分代码是这样的： Connection conn= DriverManager.getConnection(url,user,password); Statement stmt=conn.createStatement(); String sql = new String(); sql="select signal_name from repdata1_pri where rec_id like'200507172000%'"; ResultSet rs=stmt.executeQuery(sql); while(rs.next()) { temp=rs.getString("signal_name"); out.println(temp); } rs.close(); stmt.close(); conn.close(); 请高手们帮我看看这到底是怎么回事啊？
